LDN 1217, VdB 152 and friends in Cepheus
This fascinating field in Cepheus features the the dark nebula LDN 1217 (aka Barnard 175). LDN 1217 is a Bok globule - a region where dust condenses to form protostars. The dark nebula is dimly illuminated by ultraviolet light, yielding a reddish glow characteristic of Extended Red Emission nebulae (EREs). Approx. 20 hours of Ha+LRGB data from the Telescope Live remote observatory in Almeria, Spain (SPA1-CCD). Pre processing in Astro Pixel Processor, and the Post processing in Pixinsight with final touches in Paintshop Pro.
